Genesis 7:15-17

Amplified Bible

¹⁵ So they went into the ark with Noah, two by two of all living beings in which there was the breath and spirit of life. ¹⁶ Those which entered, male and female of all flesh (creatures), entered as God had commanded Noah; and the Lord closed the door behind him.

¹⁷ The flood [the great downpour of rain] was forty days and nights on the earth; and the waters increased and lifted up the ark, and it floated [high] above the land.
